About the Micro USB connection hole on the Phantom 4 Pro gimbal

[JXN]

I recently came across a Micro USB connection hole on the back of my Phantom 4 Pro gimbal, and I am not sure what it is used for.

While trying to repair my drone, I had to disassemble the gimbal to see the connection hole. I am now curious to know what it is for and whether there is any software available for it. I am wondering if DJI calls it internally and if they have any information regarding its use.

I also tried connecting it to a computer and it worked too but reads nothing at all. hoping someone might have some information about this Micro USB connection hole and its use and let me know if is possible.


Thank you!

Water damage?

If it's the one next to the link button and sd slot, it's used to install firmware from DJI Downloads or diagnose with Assistant. There is no readable info.
